The object of the invention is prirnarilj,7 to greatly prolong the liteot' the matrices. at a slight increase in the cost of manufac ture.

T o this end it consists in providing each matrix with two identicalcharacters and 'with the same character' in a different face or styleless frequently used= so 'that the use and wear of a matrix; may bedistributed between the duplicate characters and its li-c thus prolongeduntil the third and less .fre-- quently used character has becomeinopera. tivefrom use. .D

' Matrices for linot'ype machines hare heretofore been provided withthe. saine character in variant forms, so that Aeither character couldbe presented to the molll at will. Certain faces or forms are used withmuch greater frequency than others; ordinary reading characters are usedmore or black laces. iVhen, therefore, a. matrix has a4 Asinglecharacter ol eaclLtorm, it is found that the character most frequentlyused becomes Worn and inoperative and the niatrixltherefore useless.while the second character is still in good condition. In crmsequeeiceof this fact there is a large lose to the printer due to the rejc` `ionof matrices which are `in inoperative co. iition as to oneset ot characters. By providing such matrices With tivo of the frequently use-tlcharacters instead of one, we are enabled to distribute the work betweenthe two characters and thus prolong; the life of the matrix. The sameextension'of life is' also secured when the matrix is provided with twoor three, characters' identical in every respect, as they mav hepresented successively tothe mold and the wear distributed between them,the type faces produced being the same relgardw for exan'iple,

less of which character on the matrix is pre' sented tothe mold. l

Referring to the drawings: Figaro 1 1s an elevation of a. matrix withthree intaglio letters, of which tiro are identical. Fig. 2 1s asideView et the same. Fig. 3 is a side View of a modification of the saine.Fig.

l illustrates the mann r in which the matrix j shown at. liigs. 2 and 3is so applied to a mold that its lower intaglio letter is opposed to'the single cell or slot; and Fig. illnstretes the manner in which thesame matrix is so applied to the said mold that its middleintaglioletter is opposite to the single cell or slot. V

The matrix b shown in Figs. 2 and 3 is provided with three supeposedintaglio letters l. l and 2 of the same tout. l'lhe tivo letters l, labove and be. :ov are exactl)T alike, whiletne third letter 2 in themiddle is of a distinct kind. or say thicker or bolder than the lornier.'lhen the one of the tivo intaglio letters l, l is used until it wornout, alter which il other one is engaged for use in casting; tyr. lt isassumed that either of the two letters l, 1 is used more frequently thanthe third letter '2,.so that the latter may he. Worn ont about at thesaine time the other letters. We do no?l however, limit, ourselves inthis respect. lllith some of the matrices 'the third letter 2 mayrepresent a. different character, which is seldom used, as is torexample shown at Fig. 3. Figs. and 5 illustrate the manner in which thematrix Y; may be applied to the mold of an ordinary linotype machine.The mold 0 is. provided with two grooves e and el parallel to themouth'ot the single cell or slet d, and.
